The people I dealt with on the phone kept calling me and asking me to photograph different things, they also expected me to know things I had no way of finding out - they told me to ring my electric company to find the answers, the electrical company told me it wasn't up to me to chase the information it was up to Chargemaster to call them and ask about the details of my electrical system. Having said that, which was very disappointing, the young man who finally came to fit it did a superb job. Joe. He was polite, tidy, asked several times if we had questions, when I did he answered them thoroughly. Excellent. He alone bumped up my score for the company.
